PROBLEM TO BE SOLVED: To provide a mower preventing clipped grass from being caught by a joggle part provided at a tip opening part of a chute.SOLUTION: A left/right pair of blade bodies 54 substantially horizontally rotating about longitudinal shafts 45 comprise a plurality of blade pieces 54a, all of which have same length. The respective blade pieces 54a have a same phase and the longitudinal-directional parts thereof are fitted along the radial direction passing through the longitudinal shafts 45 of the corresponding disks 44. The respective blade pieces 54a are fitted to the respective disks 44 to differentiate distances from the longitudinal shafts 45 of the respective disks 44 so as to have such rotation trajectories that the tip ends of the pair of blade pieces 54a of the respective disks 44 come into contact with each other at a part where a tip opening of a chute 90 of the rear left/right central part of a housing 51 is located.
